Is a picture really worth a thousand words? ImagePulse measures how consumers feel about brands based on photos in which the brand is included. It uses a mixture of text, sentiment and image analysis to measure if the image is positive or negative and the emotions involved. What does it mean to the brand when people take pictures of themselves at a Nike store or having coffee in Starbucks?

A new study conducted by a doctoral student at Pace University, in association with Famecount (which tracks how popular brands are according to social media) concludes that social media popularity can reliably predict daily stock prices.

Imagine a technology that can read and “understand” any block of text. That’s what Swedish startup Saplo does. It’s a sort of “Pandora for text” whose ultimate aim is to filter articles, tweets, ads or any other types of text based on your preferences. It can also group together similar text items, find related ones and even judge whether the text expresses positive or negative sentiments.
